In a triathlon, every second counts. However, while most seconds are earned in the pain cave, some seconds are lost to human error, and some are simply purchased. Lucky for you, the Sidi T3. 6 Shoes cover you on all fronts. With a new design, transitions are simplified with the T3. 6's ease-to-use entry and exit system, and your efforts are maximized from its carbon sole and conforming design. From a purely functional standpoint, we can agree that rigidity is key. That's why Sidi uses a multi-step system to ensure that your power output receives a minimal amount of dissipation through the interaction of the shoe and the pedal. To achieve this, Sidi incorporated its new Eleven Carbon Composite sole. Now, don't think that this is anything like the Millennium 3 composite sole. The Eleven uses a 3K carbon fiber weave that's been inset into a carbon infused nylon matrix. This process provides variable stiffness throughout the sole in order to dramatically improve the overall stiffness-to-comfort ratio of the shoe. This especially makes the sensation of your T2 change into running shoes more seamless, because your arch movements have been accommodated over the cycling leg. And not only does the composite matrix result in comfort, but it also enhances the level of durability. In fact, Sidi estimates that the new material is less susceptible to temperature extremes and wear, and accordingly, the soles are predicted to retain their rigidity levels over multiple seasons of use. For fit, Sidi understands that triathlon plays by another set of rules. Its hallmark ratcheting system and Ergo Buckles aren't relevant to your discipline, so, Sidi incorporated a two-strap closure system, mated with a 'burrito-wrap' upper. What does this mean? Well, the T3. 6 features an opening that runs over nearly the entire top of the shoe. The burrito analogy is drawn from the T3. 6's upper construction where one layer of the upper wraps over the other. This allows you to really dial in the ...
